Pontiac Repair: my both doors wont close, weatherstrips, gread

Question
hi ,we had a cold snap last night and my doors froze open ,ive tried many ways to free them ,with no success can you help  

Answer
Hi Richard:
if the doors are frozen to the body you can use pure silicone spary on the weatherstrips and if the latches freeze up try a liquid spray gread on the latches and hinges. If the door lock cylinders freese up you can try a liquid graphite spray or a penetrating oil speay like PB blaster or better yet GM has a product called super lube it's in a spray can you can use that in the lock cylinders and on the latches and hinges as well. Good luck :0
